        <h2>Performance</h2>
        <p>
      <span class="emphasis"><em>kchan</em></span> -- a positive integer that indicates
    which channel of the software bus to read
    </p>
        <p>
   Note that the inward and outward software busses are independent, and
  are not mixer buses.  Also the k-rate and a-rate busses are
  independent.  The last value remains until a new value is
  written.  There is no imposed limit to the number of busses but they
  use memory so small numbers are to be preferred.

        <h2>Example</h2>
        <p>
      The example shows the software bus being used as an asynchronous
    control signal to select a filter cutoff.  It assumes that an
    external program that has access to the API is feeding the values
